What is the name of Laura Palmer’s diary in Twin Peaks?

Laura Palmer’s diary is titled The Secret Diary of Laura Palmer. The book was published in 1990 as a tie-in to the television series Twin Peaks and presents Laura’s writings in fictional diary form.

Jennifer Lynch, David Lynch’s daughter, wrote the book. It explores Laura’s private experiences before her death, adding background that could not be shown directly in the early television episodes. The diary gives readers access to Laura’s fears, relationships, and encounters with the mysterious figure BOB.

The book is an official part of the wider Twin Peaks story, but it is not the same object as Laura’s more ordinary school or personal notebooks seen in the series. Its title also differs from later companion books, including The Secret History of Twin Peaks and Twin Peaks: The Final Dossier.

Because several fictional documents appear in the franchise, readers sometimes merge their titles. The exact title includes “Secret Diary,” “Laura Palmer,” and no subtitle.
